I don't like... Rush.
This ought to be capital sin around here, uh?
I hate Rush.
As for U2, i'm a big fan. They're pop stars. Rock music is usually 4 or 5 chords and a catchy riff, and they've got that down really well. They write catchy melodies and record them.
Their live shows show that they work hard to entertain. Live Aid might have been their biggest accomplishment. Where most of my musical idols gave lackluster (or even embarassing) performances, U2 was noted as one of the standouts. And they continue to put on great live shows that compile music for the masses with what seems like an honest interest in engaging their audiences. Bono's onstage banter is priceless. You know that he tells the same jokes every night, but it seems playful enough to work anyway.
As for The Edge's guitar skills, i don't want to compare him to SRV, Hendrix, or anyone else. As someone who seems quite capable of playing exactly what he wants, comparing skills between artists is like apples to oranges. And if you doubt his playing, YouTube Bullet The Blue Sky from the ZooTV tour:
